Check Digit Verification of cas no

The CAS Registry Mumber 1313990-84-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,9,9 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1313990-84:
(9*1)+(8*3)+(7*1)+(6*3)+(5*9)+(4*9)+(3*0)+(2*8)+(1*4)=159
159 % 10 = 9
So 1313990-84-9 is a valid CAS Registry Number.

Ru-catalyzed asymmetric hydrogenation of 3-oxoglutaric acid derivatives via solvent-assisted pinpoint recognition of carbonyls in close chemical propinquity

Li, Wanfang,Ma, Xin,Fan, Weizheng,Tao, Xiaoming,Li, Xiaoming,Xie, Xiaomin,Zhang, Zhaoguo

supporting information; experimental part, p. 3876 - 3879 (2011/10/01)

Upon comparison of hydrogenation rates of various β-ketocarboxylic acid derivatives, β-ketoamides were found to be hydrogenated slightly faster than β-ketoesters in EtOH in the presence of [RuCl(benzene)(S)- SunPhos]Cl at 70 °C with 20 bar of hydrogen. In THF these differences were so sharpened that β-ketoamides were hydrogenated even faster than in EtOH while the esters were extremely slow. Based on these findings, a series of 3-oxoglutaric acid derived with ester and amide moieties on the two ends were hydrogenated to 3-hydroxyl products with high enantioselectivities.
